If you are not planning on running boost above 18 psi, most of the decent Chinese
offerings will do the job with either a sleeve bearing supporting the compressor/turbine shaft or sometimes there will be a ball bearing option that is not too expensive.
Key is the boost pressure/load exerted on the compressor/turbine shaft.
I looked at the website. The people are a Marketing outfit. Not a Turbo Manufacturer
like Borg Warner or Garrett. But they still might have access to some good parts.
Richard Holdener has lots of videos on different turbos he has tested over the years.
And he and his wife are very nice people.

I am disappointed though that no one in the pontiac world was willing to loan him a 57-58 Pontiac flywheel so he could run a older Pontiac engine with a turbo on it.
